Methods of and devices for reducing structure noise through self-structure analysis

Abstract

To reduce structure noise, input data representing an input structure is obtained and boundary conditions are set by classifying data of each of multiple structure elements of the input data as a signal component or a noise component. A smoothing operation is performed with respect to the input data and based on the boundary conditions. Output data representing an output structure is provided by reducing noise from the input structure.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This U.S. non-provisional patent application claims priority under 35 USC § 119 to Korean Patent Application No. 10-2016-0165559, filed on Dec. 7, 2016 in the Korean Intellectual Property Office (KIPO), the disclosure of which is incorporated by reference in its entirety herein.BACKGROUND1.

AI Technical Summary

Benefits of technology

[0009]The method and device according to example embodiments of the present disclosure may reduce structure noise efficiently with respect to an arbitrary input structure without requiring additional information on the signal components of the input structure by analyzing the data of the input structure itself to set the boundary condition and by separating the noise from the data of the valid structure. In addition, in comparison with conventional schemes of reducing noise by adding structure elements, the method and device according to example embodiments of the present disclosure may reduce the structure noise with a decreased data processing time by sequentially removing data of structure elements to simultaneously remove the errors in the data of the input structure.

Problems solved by technology

It is not easy to separate and remove the structure noise or errors from the original structure data.

The removal of structure noise may significantly increase processing time for processing the structure data.
